	i have dp type gas flow meter i use 1151 dp transmitter which calibration range is 760mmwc. actually my gas passes through 3.8 kg/cm2 at 33 deg. c. but reading in dp transmitter shows -0.4%. i check manifold and isolation valve also it is ok. theoroticaly if we calculate for our gas consumption base it will appx. 292 mmwc. can you any body says why dp transmitter not shows reading. i check dp transmitter also it is working perfecly if i isolate and give pressure for calibration range thanks hitesh

	Is it installed the right way round? __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Ditto to PW, seems like it might be hooked up backwards. __________________ Money doesn't talk, it screams in your face.

	i check manifold and isolation valve also it is ok Could you check them again? I once had a similar problem and I asked one of my technicians to check the manifold valves. He declared them as okay. Still the problem existed. Later I learned that he had only checked if they were open or closed. During the next shutdown, I led another technician to pull out the manifold and inspect it. The equalizing valve was broken. It was allowing the pressure in both ports to equalize (more or less). And just to give me peace of mind: regards, Vulcan __________________ Miscommunication: when what people heard you say differs from what you said. Make yourself understood.
